tools: mkimage: fix __u64 typedef conflict with new glibc
Including "sys/stat.h" from newer glibc will cause __u64 from linux uapi
header to be included, causing compilation failure for u-boot tools
USE_HOSTCC
Remove typedef for __u64 in include/compiler.h to fix the issue. It should be
safe because as of u-boot-2018.03, no ref to __u64 is found under u-boot tools/
directory
Error message snippet follows
